\qmltype Map
\instantiates QDeclarativeGeoMap
\inqmlmodule QtLocation
\ingroup qml-QtLocation5-maps
\since Qt Location 5.0
\brief The Map type displays a map.
The Map type is used to display a map or image of the Earth, with
the capability to also display interactive objects tied to the map's
surface.
There are a variety of different ways to visualize the Earth's surface
in a 2-dimensional manner, but all of them involve some kind of projection:
a mathematical relationship between the 3D coordinates (latitude, longitude
and altitude) and 2D coordinates (X and Y in pixels) on the screen.
Different sources of map data can use different projections, and from the
point of view of the Map type, we treat these as one replaceable unit:
the Map plugin. A Map plugin consists of a data source, as well as all other
details needed to display its data on-screen.
The current Map plugin in use is contained in the \l plugin property of
the Map item. In order to display any image in a Map item, you will need
to set this property. See the \l Plugin type for a description of how
to retrieve an appropriate plugin for use.
The geographic region displayed in the Map item is referred to as its
viewport, and this is defined by the properties \l center, and
\l zoomLevel. The \l center property contains a \l {coordinate}
specifying the center of the viewport, while \l zoomLevel controls the scale of the
map. See each of these properties for further details about their values.
When the map is displayed, each possible geographic coordinate that is
visible will map to some pixel X and Y coordinate on the screen. To perform
conversions between these two, Map provides the \l toCoordinate and
\l fromCoordinate functions, which are of general utility.
\section2 Map Objects
Map related objects can be declared within the body of a Map object in Qt Quick and will
automatically appear on the Map. To add objects programmatically, first be
sure they are created with the Map as their parent (for example in an argument to
Component::createObject), and then call the \l addMapItem method on the Map.
A corresponding \l removeMapItem method also exists to do the opposite and
remove an object from the Map.
Moving Map objects around, resizing them or changing their shape normally
does not involve any special interaction with Map itself -- changing these
details about a map object will automatically update the display.
\section2 Interaction
The Map type includes support for pinch and flick gestures to control
zooming and panning. These are enabled by default, and available at any
time by using the \l gesture object. The actual GestureArea is constructed
specially at startup and cannot be replaced or destroyed. Its properties
can be altered, however, to control its behavior.
\section2 Performance
Maps are rendered using OpenGL (ES) and the Qt Scene Graph stack, and as
a result perform quite well where GL accelerated hardware is available.
For "online" Map plugins, network bandwidth and latency can be major
contributors to the user's perception of performance. Extensive caching is
performed to mitigate this, but such mitigation is not always perfect. For
"offline" plugins, the time spent retrieving the stored geographic data
and rendering the basic map features can often play a dominant role. Some
offline plugins may use hardware acceleration themselves to (partially)
avert this.
In general, large and complex Map items such as polygons and polylines with
large numbers of vertices can have an adverse effect on UI performance.
Further, more detailed notes on this are in the documentation for each
map item type.
\section2 Example Usage
The following snippet shows a simple Map and the necessary Plugin type
to use it. The map is centered near Brisbane, Australia, zoomed out to the
minimum zoom level, with gesture interaction enabled.
\code
Plugin {
id: somePlugin
// code here to choose the plugin as necessary
}
Map {
id: map
plugin: somePlugin
center {
latitude: -27
longitude: 153
}
zoomLevel: map.minimumZoomLevel
gesture.enabled: true
}
\endcode
